I replaced my antifreeze/coolant levels earlier today and when I first started my car it worked fine, but now it only works when there's something propped up underneath the glovebox (box, passenger's foot, etc). What is it and how do I fix it?

I assume you mean the blower motor is not working? (No air coming out of the vents) if so, it sounds like the blower motor is bad which is common here is the location of the blower motor and how to change it out in the images below. Also, I have included a generic guide how to test for power and ground to confirm the blower motor failure.

The blower motor is under the dash on the right side. Check out the images (below). Please let us know what happens.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
